I finally had the chance to watch the Mellodrama DVD.
Although most of us here will not find much we didn't already know, I thought it was quite entertaining for it's length.
Markus has a lot of intelligent information to share and Streetly's absence is certainly felt.
Some minor errors trivia-wise regarding Led Zeppelin using a MK II and all 4 Beatles buying them upon release (only Lennon and B. Epstein did) but still it gives a fairly accurate picture.
Overall it's a great companion piece to Frank's book and Nick Awde's book, and I'd certainly recommend it for the layman who wants a starting point to learn about these machines and the music made with them.
